Dynamic Frameworks are only supported on >= iOS 8

[kylebshr]

Dynamic frameworks were introduced with iOS 8, and I believe cocoapods use_frameworks! will also only work on iOS 8 or greater.

FirebaseUI does support iOS 7 iirc, but that's because there are some giant hacks in place (if you look into the repo, there's no framework targets even though use_frameworks! works). This minimum version bump and abandoning the giant hacks is something I'd like to do in the very near future.

@morganchen12 that's very interesting. I also wasn't trying to say the project isn't compatible with iOS 7, just that you normally can't install with use_frameworks! on iOS 7. But you're saying the project actually will work on iOS 7 with use_frameworks!? If so, I'll close the PR :)

[morganchen12]

Ah, I see what you mean. use_frameworks! should fail on iOS 7 regardless of our hacks if we're dynamically linking, since iOS 7 just doesn't support dylibs. I'd have to take a closer look and see what's going on, but I'm hoping to override all this stuff and just bump our minimum version to iOS 8 anyway.

[morganchen12]

Yeah I lied, FirebaseUI doesn't support iOS 7 (nor should it). I'll merge this ahead of time to not mislead people.

Thanks @kylebshr!

So, FirebaseUI no longer supports iOS 7? Is this only for Swift?
